GEABING FOR TRACTOR PLOWS.

Application filed October 13, 1919.

To all whom it may concern:

Be it known that I, JOHN R. BOC-KELMAN, J12, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Missouri have invented certain new and useful Improvements in Gearing for Tractor Plows, of which the following is a specification.

This invention relates to an improved plow of the tractor type and the principal object of the invention is to provide a plow having an improved frame structure and improved driving means or means for transmitting the movement to the driving wheel from the engine of the machine.

'Another object of the invention is to provide a tractor pl ow so constructed that it may be controlled from a seat extending from the body of the frame, with further improvements to vertically adjust the frame of the machine with respect to the ground.

Another object of the invention is to provide an improved means for mounting the engine or source of power with respectto the frame and further to so constructthe machine that it will be comparatively simple in construction and will not easily get out of order or need repairs.

This invention is illustrated in the accompanying drawings, wherein:

tractor plow in top plan.

Figure 2 is a view showing the improved plow in side elevation.

Figure 3 is an enlarged fragmentary view showing the manner of mounting the supporting wheeli positioned upon the left hand side of the machine.

Figure 4 is an enlarged view of the clutch.

Figure 5 is an enlarged fragmentary view illustrating the means of mounting the front wheel in position.

This tractor is provided with a frame having side bars and 11 which are connected at their forward ends by the end bar 12. Cross bars 18 and 1a connect the side bars at points intermediate the length of the frame and serve as bracing means. They are in turn connected by the longitudinally extending bar 15 which together with the side bar 10 hold the engine or source of power 16. A propelling wheel 1? is positioned in the rear portion of the frame and provided wit-h an axle 18 journa led in the bearings 19. Two sprocket Serial No. 330,467.

wheels 20 are carried by this driving wheel 17. Driving chains 21 lead from these sprocket wheels :20 to the sprocket wheels 22 of shaft 23 journaled in the bearings ll. At one end of the shaft there is provided a large gear 25 meshing with the small gear 26 of shaft 27 journaled in the bearings 28. This shaft 27 also carries a large gear 29 which meshes with the small gear 30 of shaft 31 journaled in the bearings 32.

Upon the shaft 31 there is provided the reversing cliutoh containing the gears 34. and 35. This reversing clutch is made in the form of a tubular section slidably mounted on the shaft 31 and interlocking with shaft 31 by means of the key 86. Po sitioned between the gears 34, and 35 and meshing with one of them at all times is the gear 38 cncon'ipassing the end of the engine shaft 39 of the engine or source of power 16. The gear 38 is loosely mounte-l on the shaft 39. but is caused to rotate with the shaft 39 at times by means of the lin gers ll.

L These fingers 41 are slidably mounted in the sleeve of the gear 38 and have extending radially therefrom arms 42 each carrying at its outer end a clutch element 115. As seen in Figure 4, these clutch elements are arranged within the clutch band it which is keyed to the shaft. A clutch member 49 is slidably mounted upon the sleeve of the gear 38 and a plurality of links are pivotally connected at corresponding ends thereto and their opposite ends to the clutch element. A cooperating clutch member 48 is associated with the clutch member 4-9 whereby the latter may freely' rotate independently of the clutch member 418. This clutch member 18 is reciprocated upon the gear sleeve by means of a hand lever 45, a draw rod 45 and a bell crank it. The bell crank at? is pivoted at its angle and has its inner end connected to the clutch member 48 and its opposite end to the draw rod -15.

When it is desired to cause the gear 38 to rotate, the hand lever 45 is pulled. back thereby causing the clutch members 48 and 49 to move inwardly of the clutch band 4-1 through the instrumentality of the draw rod 45 and bell crank J. It is of course understood that the clutch band is keyed to the shaft 88 and that the inner ends of the arms 42 are movably associated with the gear sleeve, so as to be capable of radial movement relative thereto. As the clutch members move :inwardly into t-he clutch band, the links -cause the clutch elements 43 to move outwardlty and bind against the clutch band 44 thereby causing the gear 3.8 and its sleeve to rotate \Vftli "the shaft through the instrumentality of rtheaarms '42, clutcln elements 43 and clutch band 44. Outward movement of =the.'c1u'tch members 48 and 49 will obviously release the grip of the' clutch ielements upon the clutch -band, thereby permitting the idleness =of' the gear .Ei'ther t'he gear '34 or the gear may -*be is the-worm-58and' the gear-59 which meshes Y with the gear 60 4of shaft 61. At the =op-' posite end-o'f the-shaftf61 the gear 62 meshes with the gear 63 of shaft 64 journaled in the bearings 65 and 65 and carrying at its end the hand wheel66. Thus by-operating the hand wheel 66 the gears 62 and 63rotate which causes the shaft-61 to 'rota'tewhich in turn causes the shaft 57 to rotate through the medium'of gears 59an'd 60, hence *the worm 58 which meshes with the teeth '67 of stub shaft 55 vertically adjusts the stem 54. In the same manner the hand wheel 70 mounted upon shaft 71 actuates the gear 68 meshing with the ;gear 69 of shaft 74 which carries a worm asshown in Figure 5. This worm meshes with the teeth of stub shaft; also as shown in Figure 5 it vertically adjusts the pin 72 -of stub shaft of wheel 76;

This machine is provided with steering shaft 77 on which is mounted the hand wheel 7 8 and the worm 79 which :engages the rack teeth 80 of the lever plate '81 journaled upon the pin '82 and terminating in the oblong bearing head-'83 engaging one end ofthe lever join-na led upon p'inf86. Linkst-BT' and 87" extending from 13 116 183 61 85 connect with the links 88' and 88 termi-nating in the bearing heads 89 and 89 55tand 74 of wheels 56 and 76. Hence by operation .of the hand wheel 7 8 the Wheels 56 and7'6 will 'be simultaneously moved and -.therefone a turn can be easily and safely made with this machine.

then this tractor ,plow is in use, the engine is started and by means of the mechanism previously described, the ma'chine may be driven across-the fields. The machine will be steered in the proper path through the medium of the steering gear and thus th'e plow blade will be causedto cut in proper're'lation'to a furro-w'previously formed or also through the proper adjustment of stem 7 5 a new furrow may be formed.

What-I claimis:

A tra'c'tor comprising a frame, a transversely extending axle rotatably carried by the frame, a single -traction wheel "mounted upon the axle and dispose'dwith'in the frame, relatively large drive-sprocket wheels secured to the axle on'each side ofthe traction wheel, an engine carriedbysai'd frame in advance of the traction wheel including a longitudinally extending centrally disposed -drive shaft, a drive gear upon the shaft, clutch means for connecting'and disconnecting the gear with the drive shaft, a trans-verse gear shaft arranged between the engine andtraction wheel, a vgear keyed to said shai'ft, a -second shaft journaled on the frame 'a large gear carried by said second shaft for meshing with aforesaid gear,said second s'ha'ftalso being provided with a relatively small gear, a third shaft extending transversely of'the frame, a relatively large gear carried by said last mentioned shaft for meshing with the relative small gear of the second named shaft, a pair of relatively small sprocket wheels carried by the third shaft, and sprocket chains connecting the last mentioned sprocket wheels with-the first mentioned sprocket Wheels and means including reversing gears slidably mounted upon the first mentioned shaft for engaging the opposi te side of the drive gear "wheel.
